PURPOSE:To facilitate the formation of data and enable the quantity of data to be reduced by providing a means which forms a positioning command data with the minimum positioning distance of a workpiece as a unit and stores said data, and a means which converts said data into a unit of distance when sending out said data to a machine tool. CONSTITUTION:A command data is formed by a central unit, etc., transmitted through a transmission controlling part 3, and stored by a command data memory part 21. And, when a workpiece is set in an NC machine tool 9 completing preparation for machining, a CPU extracts command data in order out of the data memory part 21 according to a machining order and send them out to a converting part. Then, the converting part 22 interprets the command data and, when a data is a positioning command data, it converts each of X, Y, and Z data into a defined technological value, while giving other data to a transmitting part 6 as they are, leaving data transmission to the part 6. Then, an NC device 10 gives a motor driving data, etc. to a machine tool 11 based on data, carrying out commands. A control part 2 monitors the execution of commands through an interface part 7, and sends out the next data when it is completed.
